WEIGHING-MACHINE.

SEEOIFICATION forming part of Letters Patent No. 708,799, datedSeptember 9, 1902.

Application filed June 6, 1901.

To all whom it may concern:

Be it known that I, EDGAR l-I. COOK, a citizen of the United States,residing at the borough of Brooklyn, in the county of Kings, city andState of New York, have invented an Improvementin Weighing-Machines,ofwhich the following is a specification.

My present invention relates to improvements upon the devices shown anddescribed in my patentofDecember 18,1900,N0. 664,313. In addition tothese features my present invention relates especially to attachmentsfor weighing-machines by which it is possible to register the number oftimes that the machine has been in operation and simultaneously withsuch registration and the operation of the machine to set in motion amusic-box mechanism for the production of musical sounds.

The device of my present invention, like the device of the aforesaidpatent, relates particularly to machines in which the indicatordial isconcealed beneath an ornamental face, there being an opening in the faceand a shutter over the opening normally concealing the weight upon thedial behind the shutter, the said shutter being actuated by a personupon the platform of the machine after the insertion of a coin todiscover the weight.

In my present invention the case, the platform, its lever, and the otherparts of the weighing mechanism shown areof usual character, and theupper part of the case is provided with an ornamental face having anopening in one side thereof. The indicatordial is concealed beneath theornamental face, the opening coming at the weight indications and acentral pointer being provided to indicate the weight after the removalof the shutter. In this device I provide an operative mechanism, suchoperative mechanism being by preference a coin -actuated device, themeans for actuating this mechanism being adapted to move an arm to whichthe said shutter is connected, so that after the person to be weighedsteps upon the platform and operates the weighing mechanism the shutteris moved away from the opening in the ornamental face, so that theperson upon the Serial No. 63,367. (No model.)

tive mechanism, and which devices are actuated simultaneously with theactuation of the shutter mechanism for effecting the registration of thenumber of times that the machine has been in operation and forsimultaneously setting in motion a music-box mechanism for theproduction of musical sounds.

I do not herein claim as new any part of the registering mechanism per.96 nor of the music-box mechanism in itself.

The special devices of my invention are hereinafter more particularlydescribed.

In the drawings, Figure 1 is an elevation of the. case, the weighingmechanism, and most of the operative parts with the outer face brokenaway and with the music-box mechanism superposed upon the case. Fig. 2is a plan view, and Fig. 3 a side elevation, in larger size than shownin Fig. 1, of the devices simultaneously acted upon by the operativemechanism for effecting the registration, operating the shutter, andsetting the music mechanism in motion. Figs. 4, 5, and 6 are detailedviews, in larger size, of parts of the music-box mechanism.

a represents the case of the weighing-machine, which may be of anydesired character or configuration. This case contains theindicator-dial 1) upon an axis 2. The axis 9 carries a pinion 3, and arack 4 engages the pinion 3, the lower end of the rack being connectedto the cross-head 5. A rod 6 extends downward from the cross-head 5 tothe lever of the weighing-platform, which latter parts are not shown.Between the cross-head 5 and the upper cross-head 8 there are helicalsprings 7, connected to said parts at their respective ends. Thecross-head 8 is connected to a bell-crank supporting-lever 9, pivoted toa stud 10 upon the case, the free end of the bell'crank lever 9 beingprovided with an adjusting-screw 12, there being stops 11 upon oppositesides of the free end of the said lever, the screw 12 providing for theapplication of the proper tension to the springs. These parts justdescribed are old in weighing-machines of this class, and I therefore donot claim the same.

The face 0 of the weighing-machine occupies a position in front of theindicator-dial b, and said face may be ornamented and made attractive inany desired manner, the face being of such a character as to cause theindicator-dial behind the same to be invisible. At one side in the face0 I provide a rectangular opening 0, disposed vertically, and anadjacent pointer upon the face is centrally located with reference tothe said opening, the said pointer being preferably on an imaginaryhorizontal line drawn through the axis of the weighing-machine. Ashutter 61 occupies a position behind the face 0, normally covering theopening 0 therein. This shutter is larger than the said opening and ismounted upon an arm d, connected to a hub d and which hub preferablycarries a second arm C1 The arm (1 is between the face a and the dial 1)and the arm (1 behind the dial b. The hub 61 is upon a stud projectingfrom the hack of the case of the machine, and from the said huhextending downward there is an arm which is practically a continuationof the arm d and which arm carries the same letter of reference. Aswinging movement is imparted to the arms d (Z and the shutter 61 uponthe huh (I by a suitable operative mechanism. 1 I

I do not limit myself to the details of the operative mechanism; but forthe purpose of an operative mechanism I have illustrated the followingparts: A handle 6, connected to a crank-arm e, is in turn pivoted byashaft 14 to a frame f, the said parts being within the case and thehandle (3 projecting through a curved mortise in the case. The crank-arme carries a stud 15, passing through a curved slot 16 of the frame f,and the said stud on the other side of the frame is connected to areciprocating plate 9, moved back and forth by the handle 6 and crankarme and the said stud, and to insure the return movement of these parts Iprovide a spring t', with one end fastened to the framefand the otherend to a projection of the reciprocating plate g. I provide a slideway17, formed as a continuation of the frame f, and a pin or projection 18,connected to the reciprocating plate g, the pin or projection movingover the slideway and adapted to come againstthe lower end of the arm d,which is adjacent thereto, so as to swing the arms d d and move theshutter 61. The movement of the handle device and this reciprocatingplate g thereby effects this swinging movement and removes or retractsthe shutter 01 from the opening 0 in the face 0, so that the weight maybe discovered upon the dial.

My present invention relates particularly to the parts hereinafterdescribed and which parts are acted upon by the operative mechanismhereinbefore described, said action being simultaneous with theoperation thereby of the shutter mechanism, so that the shutter isoperated, the registration effected, and the music-box mechanism set inoperation withone movement of said operative mechanism.

A stud 7a is secured to and projects from the case a. Upon this stud isa sleeve Z, held to the stud by a screw 19. I employ arms mm, and 0 andasupport 20, which parts are preferably formed integral with the sleeveZ and bear the relation to one another shown in Figs. 1, 2, and 3 of thedrawings. A spring 21 is fastened at one end to a pin of the case a, andthe other end thereof passes through an opening in the arm on to holdthe sleeve and the series of arms in a predetermined position, in whichthe upper end of the arm n comes against an adjustable stop 33 upon thecase. A spring 22 is secured to the support projection 20 of the sleeve,and I provide an eccentric 23 upon the free end of the arm 0. Thiseccentric is held in place by its stem, which passes through the arm0,and on the end of which stem isaclamping-nutbearing upon the oppositeside of the arm 0. (See Figs. 2 and 3.) An auxiliary arm 0 is pivoted tothe arm 0,

and'the free end of said arm 0' has a sidewiseprojecting lug. There is apin 24 projecting from the back of said arm 0 and upon which the spring22 bears to force the said arm 0 against the surface of the eccentric23. By reference to Fig. 1 it will be noticed that the position of theauxiliary arm 0 with reference to the eccentric 23 is practically at itsextreme limit and that with the turning of the eccentric said arm ismoved toward the left hand, in which the spring 22 is strained to agreater extent. A rod 25, pivoted to the free end of the arm m, extendstherefrom to the registering mechanism r. Projecting from the surface ofthe arm n is a hollow hub 26, mortised in opposite sides, and in thishub is a spring-actuated tooth 27. A pin passes through this tooth andthrough the mortises of the hub to limit the outward movement of thetooth and to prevent the tooth turning in said hub, the extent of theinward movement of the said tooth being controlled by the spring.

A bracket 28 projects from the case Ct, (see specially Fig. 3,) and avertical rod sis journaled at its lower end in said bracket and at itsupper end in a bracket 34: of the case of the music attachment. Near thelower end of the rod .9 is a toothed wheel 29, engaged by the aforesaidspring-actuated tooth 27. At the upper end of the rod .9 is a star-Wheel30. Arms 35 36 project from a common bracket secured to the case of themusic attachment.

t represents the case of the train of gears or other device foractuating the toothed wheel '1], and the shaft of the governor toprojects from this movement-case 15 and its upper end has a bearing inthe forward end of the arm 36.

A pivoted lever to is connected to the forward end of the arm 35, andthe same is provided with a finger 37 and with an arm 39, and thegovernor-shaft is provided with a spring-arm 40. The toothed wheel '1)is provided with a mortise, and a spring-actuated slide operates in thismortise and is connected to the toothed wheel. This slide is formed IIOof two plates upon opposite surfaces of the toothed Wheel,connectedthrough the mortise by a screw, and between these plates is a helicalspring, with one end bearing upon the toothed Wheel and the other uponthe slide. Figs. 4, 5, and 6 show the normal or position of rest ofthese parts, in which the finger 37 occupies a position in the saidmortise of the toothed wheel 1;, partially retracting the said slide 38.In this position the arm 40 of the governor is engaged by the arm 39 ofthe lever it, and a pin 42, also formed on the lever u, but on its otherend, is in engagement with the star-wheel 30. i

In the operation of the parts and with the movement of the operativemechanism hereinbefore described the projection 18, moving over thesurface of the slideway 17, comes simultaneouslyinto engagement with theend of the arm 0 and the lower end of the shutter-arm d and moves saidshutter-arm and shutter and at the same time swings the arms on n 0 andthe auxiliary arm 0, these parts moving with and by the projection 18 tothe limit of its movement when they are released. In this movement thespring 2i is put under tension, the rod 25 has been moved to effect theoperation of the registering mechanism 7', and the spring-tooth 27 hasbeen moved over the surface of the toothed wheel 29 to a point where thesaid tooth engages with one of the teeth of said wheel. The returnmovement is effected by the contraction of the spring 21, which inmoving the arms m, n, and 0 back to the normal position, Fig. 1, turnsthe toothed wheel 29 and the vertical rod 5 and the star-wheel 80,swinging the lever Lt and withdrawing its finger 37 from engagement withthe toothed wheel "0 and its arm 39 from engagement with the arm 40. Themusic mechanism is th us released and in its operation produces musicaltones for the entertainment of the person upon the platform while beingweighed. The movement of the star-wheel 30, actuating the lever u, putsunder tension the spring 41, so that when the pin of the lever u passesinto the next notch of the starwheel the spring 41 returns the lever uto as nearly as possible the normal positionthat is to say, with thepoint of the finger 37 against the surface of the toothed wheel n. Themusic mechanism continues for one rotation of the toothed wheel 1; inthe direction of the arrow, Fig. 1, and when the edge of the slide 38comes around against and contacts with the finger 37 the finger acts tomove back the slide and uncover the mortise therein with the furtherforward movement of the toothed wheel 1;, and as soon as sufficient ofthe mortise is uncovered the spring 41 draws the point of the fingerinto the opening, and as soon thereafter as the arm 40 of the governorrotating therewith comes in contact with the upturned end of the arm 30the movement of the parts is arrested until again actuated by themovement of the lever device by the operative mechanism hereinbefore setforth, when the movement of the parts is again repeated in the mannerdescribed. It will thus be observed that the movement by the operativemechanism of the lever device simultaneously effects the registration,operates the shutter mechanism, and sets in motion the music boxmechanism. The eccentric 23 is useful for the adjustment of theauxiliary arm 0 to bring its outturned end into substantial alinementwith the lower end of the shutter-arm d, but principally to adjust theposition of the lever mechanism, so as to impart the requisite amount ofmovement to the rod 25, extending to the registering mechanism, and tothe spring-actuated tooth 27 for operating the rod 3 and the toothedwheels 29 and 30.
